Remember the milk command line interface

using rtmapi library patched to work with the new version of ruby-libxml ( libxml version > 2.7) if you’re using an older version of libxml please refer to the old (and maybe better..) rtmapi gem.

To make the cli work you have to obtain an api key and an api secret for remember the milk.

Ask them at: www.rememberthemilk.com/services/api/keys.rtm

puts those keys in a .rtm file in your $HOME the file is supposed to be in YAML format

example:

  • key: yourkey

  • secret: yoursecret

  • tz: your timezone (UTC, GMT etc..)

Than you have to authorize the app and obtain the authorization token start thartm command line interface (executable is named rrtm for brevity) and you’ll be prompted for an url

The auth method could be better. I now.. give me some time :)

Note on Patches/Pull Requests¶ ↑

  • Fork the project.

  • Make your feature addition or bug fix.

  • Add tests for it. This is important so I don’t break it in a future version unintentionally.

  • Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)

  • Send me a pull request. Bonus points for topic branches.

OLD readme from rtmapi gem ==========¶ ↑

NOTICE: v0.4+ breaks the API written for v0.3. In order to speed things up (a lot), I no longer use the REXML parser, but do it with libxml. And I turn string keys into symbols, except for rtm_ids.

If none of this paragraph makes sense to you, just read on…

This is a very bare bones API for Remember the Milk that does a minimum of error checking but should be good enough.

This is also a bare bones explanation of the Ruby portion.

You need to read www.rememberthemilk.com/services/api/ and familiarize yourself with the RTM API.

The purpose of this code is to take care of all the grunt work in interacting with the API. The rest of this document assumes you know how to use Ruby, have a net connection, etc.

To get started, you’ll need

  1. libxml installed. if you are reasonably lucky, a simple

sudo gem install libxml-ruby will do the trick. If that fails, you probably need other packages (see libxml.rubyforge.org/install.html for more info)

You may also want to install tzinfo (sudo gem install tzinfo)

  1. An RTM API KEY. See: www.rememberthemilk.com/services/api/keys.rtm

You’ll get back an email with an API_KEY and an API_SHARED_SECRET

  1. Here’s a program to test if your API key is any good. I suggest

just doing this in irb.

require ‘rtmapi’

rtm = RememberTheMilk.new( “YOUR_API_KEY”, “YOUR_API_SHARED_SECRET” ) echo_data = rtm.test.echo( ‘my_arg_1’ => ‘my_value_1’, ‘foo’ => ‘bar’ )

echo_data.my_arg_1 # should be ‘my_value_1’ echo_data.foo # should be ‘bar’

method_names = rtm.reflection_getMethods() methods_names.size # as of now (Jun 28, 2006), there are 47 methods…

  1. Getting an authorization token.

In order to do anything interesting with the API, you have to get a token that authorizes you to manipulate the data in an account. The API documentation covers the different modes of authentication at www.rememberthemilk.com/services/api/authentication.rtm (you can skip past “signing requests” – the API takes care of that for you)

Here’s a program to print out a URL that you can go to in your browser.

This will let you get a Token you can use for programming.

require ‘rtmapi’ rtm = RememberTheMilk.new( “YOUR_API_KEY”, “YOUR_API_SHARED_SECRET” ) puts rtm.auth_url # returns http://.…..

if you visit that URL in your browser, you’ll be asked to authorize. After doing so, you’ll either be given a frob value or, if you specified a callback URL, your browser will be redirected there with a frob=XXXX paramater appended on.

you can then take that frob and get an auth token (and store it in a DB or whereever)

require ‘rtmapi’ rtm = RememberTheMilk.new( “YOUR_API_KEY”, “YOUR_API_SHARED_SECRET” ) auth = rtm.auth.getToken( ‘frob’ => FROB_VALUE_YOU_WERE_GIVEN )

auth.token # the token (also, auth would work) auth.perms # the perms it has (default is ‘delete’) auth.user # a hash of the user object (id, username, fullname)

Return Values


The Ruby API library tends to return RememberTheMilkHash objects (except for tasks, see below).

These are like normal hashes, except they implement convenience methods. They also expect most of their keys to be symbols, except for when rtm_id’s are used as keys E.g.,

hash = RememberTheMilkHash.new hash = 6

hash.a_key # returns 6 hash.a_key = 4 hash.a_key # returns 4

lists = @rtm.lists.getList lists.keys => [‘43254’,‘23424’,‘23424’] lists.rtm_id => ‘43254’

Note, you can’t initially set a value using the convenience methods, and if you access one for which there is no key, it’ll throw an exception.

Also, if you want to access a parameter that is already a ruby keyword (e.g., ‘methods’), you’ll have to use the standard hash accessors:

hash will work hash.methods will NOT work (you’ll get a list of methods that work on a RememberTheMilkHash)

[for id specifically, I created a helper method, rtm_id, so hash.rtm_id will work and overrode ‘id’ so that if there is an rtm_id, you get that, otherwise you get the object id. And ‘id’ is deprecated, so I don’t feel too guilty about that.]

In general, you can look at the API to get a sense of whether the ruby code will return a Hash, an Array, a String, or a boolean. Also, you can look at the test code.

If you want to be able to dereference non-existant keys without having an exception thrown (dangerous for coding!), do: RememberTheMilkHash::strict_keys = false and you’re all set.

For many of the write methods (e.g., rtm.contacts.add), a transaction id and the newly written object are returned by the RTM API. I used to just have the Ruby wrapper just returns the transaction id info, throwing away whatever the particular object is. Now, it returns the modified object with an additional element in the hash ‘rtm_transaction’ which contains a hash of info about the transaction (the id and if it is undoable)

The test code itself is a little fragile, as it assumes it is accessing a particular account that your API key can’t access. To get around this, I created a cache of the returned data from RTM. This means that the tests for you won’t contact the RTM server, so you’ll have to trust that the net communication part works :)

Tasks


Tasks get put into a RememberTheMilkTask, which is just this:

class RememberTheMilkTask < RememberTheMilkHash end

But this will allow you to add special functionality to tasks (e.g., mixin Enumerable and define <=> based on whatever rules you’d like). If there is interest, we can do the same thing for groups, lists, etc etc.

RememberTheMilkTask also has a number of helper methods, so you can do this:

task = @rtm.tasks.getList.values.values # grabs 1st task off of first list returned by API modified_task = task.setTags “tag1,tag2” modified_task_2 = modified_task.addTags “tag3” modified_task.tags => [‘tag1’,‘tag2’] modified_task_2.tags => [‘tag1’,‘tag2’, ‘tag3’]

all the methods for rtm.tasks.* have helper methods defined (except for getList)

Dates


For now, I convert incoming due dates in tasks to a Time object. I don’t bother converting all the other dates, but if someone needs those converted too, let me know. To convert a Time object to a string RTM expects, do Time.now.iso8601 # now time in RTM-expected format (ISO-8601)

To convert an ISO-8601 time to a Time object, do Time.parse(string): now = Time.now now == Time.parse( now.iso8601 )

For more info, see www.rememberthemilk.com/services/api/dates.rtm

RTM will keep track the users’ local timezone. The API can do this automatically, but you need to require the tzinfo lib first. See: tzinfo.rubyforge.org/ for more info. The default is to give parsed dates in the user’s local timezone if tzinfo has been required. If you are writing a rails app, I recommend putting the tzinfo stuff under ~/lib (along with rtm.rb), and in your environment.rb, add this: ActiveRecord::Base.default_timezone = :utc # Store all times in the db in UTC ENV = ‘UTC’ # This makes Time.now return time in UTC

(I did my testing with tzinfo-0.3.3)

Incidentally, at the moment, rtm.tasks.setDueDate assumes the date is in the user’s timezone when it is running with :parse => 1 The RTM folks may change this behavior in the future.

If you don’t want dates converted to the user’s local TZ, do @rtm.use_user_tz = false

For now, we cache a user’s timezone info (cache index is keyed off of auth_token) so it’s not too painful to convert a ton of dates. You can call @rtm.logout(auth_token) to erase the cache for that user. I need to make that a cleaner interface.

Exceptions


If the RTM API returns an error, the Ruby API throws a RememberTheMilkError. There are getters for the raw XML response, the parsed error code and the parsed message:

error.response # returns a REXML element error.error_code # returns a FixNum error.message # returns a string

Debugging


To see copious debugging output, rtm.debug = true

This will show you the method calls being made, how they are being packaged, and what the raw (XML) response from the server is.

Other stuff


  1. I made heavy use of method_missing so you could write nice looking method

calls. E.g., rtm.reflection.getMethods()

instead of

rtm.call_api_method( ‘reflection.getMethods’ )

As long as the RTM API doesn’t conflict with Ruby keywords, we should be all set. You can always directly invoke call_api_method() if you need/want to.

  1. You can use symbols or strings in a RTM method call, and if you

use a Fixnum, it gets converted to a string. so, these are all equivalent: rtm.test.echo( ‘arg1’ => ‘value1’, ‘arg2’ => ‘666’, ‘arg3’ => ‘foobar’ ) rtm.test.echo( :arg1 => ‘value1’, :arg2 => 666, :arg3 => :foobar ) rtm.test.echo( :arg1 => ‘value1’, ‘arg2’ => 666, ‘arg3’ => :foobar )

(We just blindly call to to_s() on every argument to package it up for a method call to the RTM API)
